A cross-reference listing means this part may be a suitable replacement for the listed part numbers. Always verify fitment before installation.
IMPORTANT INSTALLATION NOTES:
✔ Fully depressurize the trailer air brake system before removing or installing the valve.
✔ Confirm one 3/8" control port, one 3/4" reservoir port, and four 3/8" delivery ports.
✔ Verify the application requires a nominal 1.5 PSI crack pressure and nipple-mounted configuration.
✔ Install the compatible 6003 or 6006 mounting nipple and apply air-system-compatible thread sealant sparingly.
✔ Pressurize the system and verify balanced brake application, release response, and no air leakage.
